About the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X225-10
The AirTAC MBLCJ20X225-10 is a compact double-acting mini cylinder featuring a rear travel stopper and tunable air cushions at both ends. The rear adjuster trims up to 10 mm of travel, creating a usable extension window of 215 to 225 mm. Delivering 157 N of push force at 0.5 MPa, this unit is built for lighter loads requiring precise end-position tuning. The riveted aluminum barrel keeps the frame small for tight machine spaces, while the 20 um hard-chrome plated carbon-steel rod resists wear.
Unlike the standard MBLJ which relies on a fixed rubber bumper, this model uses screw-tunable pneumatic cushioning to decelerate the payload smoothly before the end of stroke. Note that this specific SKU lacks a built-in magnet, meaning it cannot support CMSG, DMSG, or EMSG position sensors. The G1/8 port and M8x1.25 rod-end thread are standard for this 20 mm bore size.

The rear stopper sets the end position — it is a travel stop, not a lock. Overall length = A + 2 × stroke + adjustable stroke. MBLJ/MBLCJ mounting is Basic / FA / LB only (no SDB, no back-cover code). Thread options: PT / G / NPT.
Theoretical Output Force (Ø20mm)

| 0.5 MPa | 157 N | 132 N |
| 0.7 MPa | 220 N | — |
| Max (@1.0 MPa) | 32 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a margin.

Where the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X225-10 Is Used
PCB Depaneling Saw
Feeds a circular saw blade carriage across a 215-225 mm window. The 157 N push force handles the light carriage weight, while the tunable air cushion prevents jarring stops that could crack circuit boards.
Microfluidic Valve Actuation
Drives a lever arm to open and close diagnostic fluidic valves. The 10 mm rear stroke adjustment allows exact calibration of the valve seat depth without machining mechanical spacers.
Thin Film Web Guide
Shifts a small idler roller to align polymer films in a coating machine. The adjustable pneumatic cushion absorbs the kinetic energy of the fast-moving roller assembly to protect the lightweight aluminum end covers.
Is the Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X225-10 the Right Cylinder?
Choose this 20 mm bore when you need exactly 157 N of push force at 0.5 MPa with fine end-of-stroke tuning. If your application requires less force, there is no smaller bore in this series. If you need to step up, the 25 mm bore offers 245 N of push force at 0.5 MPa. Because the 225 mm stroke approaches the 300 mm maximum limit for this bore, the 8 mm rod is susceptible to bending under lateral stress—an external guide is strongly recommended to prevent side-load damage.
This MBLCJ variant differs from the MBLJ by offering adjustable air cushions rather than a fixed bumper, protecting the end covers during faster cycling. The rear 10 mm adjuster sets the travel end point but acts only as a mechanical stop, not a load-holding lock; the pneumatic cushion solely decelerates the piston. Mounting is restricted to Basic, FA (flange), or LB (foot) styles, as no back-cover or SDB pivot options exist for this body. Replacement matching requires the 20 mm bore, 225 mm stroke, 10 mm adjust code, PT thread, and no magnet.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Adjustable window fits your end position
- ✓ Adjuster is a travel stop, not a lock
- ✓ Magnet (S) for sensors?
- ✓ Side load — add a guide on long strokes
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Set the rear stopper for the end position (a travel stop, not a lock).
- check Avoid side load; add an external guide on long strokes.
- check Mounting: Basic / FA flange / LB foot (no SDB, no back-cover code).
- check Installation by qualified personnel per AirTAC docs.
Airtac MBLCJ Adjustable Mini Cylinder MBLCJ20X225-10 FAQ
At 0.5 MPa, the push force is 157 N and the pull force is 132 N. At 0.7 MPa, the push force increases to 220 N. The maximum theoretical force is 32 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
This specific SKU does not have a built-in magnet, so it cannot accept CMSG, DMSG, or EMSG position sensors. Additionally, the 10 mm rear adjuster is a travel stop that sets the 215-225 mm stroke window, and the air cushion only decelerates the piston; neither component mechanically locks or holds the load in place.
